摘要：NOVELTY - The present invention discloses one kind of flaky Ti-Si molecular sieve catalyst for direct propylene epoxidation, and features that the catalyst has non-acid SiO2 carrier and Ti-Si molecular sieve of the general expression xTiO2 .(1-x)SiO2. The catalyst has relatively high strength, excellent product diffusing performance and less falling off. When it is used for the epoxidation reaction between propylene and hydrogen peroxide, the catalyst can reach hydrogen peroxide converting rate up to 94.5 % and epoxy propane selectivity up to 91.0 %. It has high stability and maybe used in industrial production.
